Hi,
Status update,
I didn't have time to look into this too deep into my previous matter
so I downgraded my system and the locale works smoothly.
Now I have come to a problem with the money_get facet and made a
sample program displaying my problems (see below).
In the output you can see:
"123,00" - error parsing: (state==6) parsed=
"123,00 " = 12300
What is the problem here? Why does money_get need an ending space?
Thank you in advance,
BRGDS,
Jens Berlips

Hi All,
I recently updated gcc to the newest version in debian unstable and
suddenly all c++ locale stopped working but the old-fashion c-api
still works.
OK
==
p = setlocale(LC_ALL, "en_US");
lc = localeconv();
std::cout << lc->decimal_point << std::endl;
NOT OK (throws runtime_error)
=======================
std::locale loc("en_US");
output: [[
terminate called after throwing an instance of 'std::runtime_error'
what(): locale::facet::_S_create_c_locale name not valid
Aborted
]]
What am I doing wrong with my locales?
OBS: std::locale loc("C") is also ok.
System info
=========
The output of "locale -a" includes "en_US", it has been generated
using locale-gen, the gcc-4.1-locales, and gcc-4.2-locales packages
are both installed.
I have tried:
ii g++-4.1 4.1.2-12
The GNU C++ compiler
ii g++-4.2 4.2-20070609-1
The GNU C++ compiler
(for an output of g++ -v see (3) below)
They both give the same problem. For an output of "ldd" see (1) below.
The source code of my test application h1.cpp can be seen below (2).
Debugging libstdc++
===============
I have tried to debug the libstdc++ library, but gdb doesn't allow me
to step inside the libstdc++ library functions (ex. std::locale
constructor), im using:
g++ -D_GLIBCXX_DEBUG -g -Wall h1.cpp -o h1
to compile my program.
The debug library has been installed.
ii libstdc++6-4.1-dbg 4.1.2-12
The GNU Standard C++ Library v3 (debugging f
What is the correct way to compile my program to be able to debug
"inside" libstdc++, that is, not only the headers (then -g is enough)?
Thanks in advance!
Best regards,
Jens
